Which sign is most characteristic of mild hypothermia?

• A. LOC
• B. Cessation of shivering
• C. Hyperreflexia
• D. BP within norms

Answer: (B)

Shivering is the body's main heat-producing response in the early stages of hypothermia. In mild hypothermia, this shivering is typically present as the person tries to generate heat and stay warm. When shivering stops, it signals that the body's thermoregulatory system is failing and hypothermia is advancing toward a more severe level. Therefore, the cessation of shivering stands out as a key change you’d notice on someone transitioning from mild hypothermia toward deeper cold exposure. Other signs listed aren’t as specific to mild hypothermia: loss of consciousness points to more advanced hypothermia, hyperreflexia isn’t a typical hallmark, and normal blood pressure isn’t a defining feature.
